KeySmart Safe Box Opener - Key-shaped Safe Package Opener For Everyday Carry, with Finger Protection Fits Perfectly on Keychain or Inside a KeySmart - Great Stocking Stuffer (Black)

I love this for my teenaged drivers. It looks like a key that they put on their keychain. No one knows that it is a knife and they have a little extra sense of safety when they are out at night. I recommend this.

Keep it with my mail box key

Don't do what I did and use this straight on a box....it is a semi rigid piece of plastic in the shape of a key. It will dull quickly or bend if you apply pressure sideways instead of straight onto the "blade edge". Best to be used to puncture packing tape on a box to help open a box (like from amazon), or even to gently slice through gift wrap on a present. But it isn't durable enough to cut boxes.TLDRIs it safer than a knife? Yes.Can you use it to cut up boxes? NoShould you try anyway? Not unless you want to render it useless.What should it be used for? Cutting through packing tape or wrapping paper.

It's advertised as "ultra-durable", but it seems pretty flimsy. It came out of the box with a noticeable divot in the blade. I tested it by opening the tape on the bottom of the box it came in, and it already shows visible signs of wear. See the attached images. Last image is after testing.It also didn't open the box very well. I had to run over each length of tape about 3 times to get it open. You'd probably be better off just using an actual old key.

it’s funny

You’re better off just using your actual keys. Not durable, got dented on the first use. And pretty much doesn’t cut. I can basically just cut tape, your better off cutting the tape with your key.Would not recommend.

I've been looking for a keychain boxcutter for opening packages. This is it! I doubt that TSA will take this away from me.

You'd figure that a key-shaped thing from a company called KeySmart would make a tool out of a durable material, like a key perhaps, not one that's already showing dents after using it two or three times. I suppose they call it "PA46" to sound fancy and try to play it off. But it's just a thin piece of plastic that weighs basically nothing. The credit card that's already in your wallet is more durable than this. You could cut a scrap out of a bottle of soda and it would probably also be more durable than this. And it wouldn't cost six dollars. There's a reason there's an option to buy this as a 3-pack. The only reason it's two stars instead of one is that it's *technically* fine for the one stated purpose of cutting through basic tape (good luck with reinforced tape, and certainly not actual boxes). But y'know, real keys made of real metal are good at that too. And it'll last for years instead of maybe a couple weeks. A versatile EDC tool this is not.
